Holder for swivelling panels or the like

ABSTRACT

A holder capable of being fixed on a wall or support column carries swivelling panels which can be hung in the area of opposite front sides on pins formed from pairs of pins. The holder is provided in the area of a receiving cavity with clamping jaws which are suitable for mounting roller-shaped inserts useful for fastening the holder to support columns.

BACKGROUND OF THE INVENTION

The invention relates to a holder for flip boards and/or flip pocketsand flip sheaths which are provided in the region of the upper and lowerend of one of their edges with swivel bearings for pins arranged in eachcase in a row at the upper and lower edge of the holder.

Holders of the above type are widely used, inter alia, in offices,laboratories, workshops and supermarkets. They are easy to manipulateand permit the user rapid access to information contained in subjectindexes, lists, standard sheets, price lists and similar documents. Inorder to be able to take account of different spatial features, theholders are regularly constructed such that they can be fastened both onwalls and on holding columns. Holders are known in the case of which useis made for both abovementioned types of fastening of screws which arescrewed either as wood screws into wall plugs, or as threaded screwsinto threaded bores of holding columns. The known holders are incapableof providing full satisfaction to the extent that when used inconnection with holding columns they do not permit a change in positionof the holder with respect to the column.

SUMMARY OF THE INVENTION

It is the object of the invention to provide a holder which with the aidof easily exchangeable accessories permits both the angular position ofthe holder to be set with respect to the longitudinal axis of a holdingcolumn, and the height of the holder to be set on the holding column,and which moreover is suitable in a known way for wall fastening. Thisobject is achieved in the case of a holder of the generic typeconsidered by virtue of the fact that the latter has a basic body withclamping jaws which are suitable for mounting a roller-shaped insertwhich can swivel about an axis running transverse to the longitudinalaxis of the pins and is provided with a transverse bore for a holdingcolumn.

The holder according to the invention offers the advantage that, inconjunction with accessories formed by roller-shaped inserts, it can bemore effectively adapted than known holders to spatial andapplication-specific features. The use of clamping jaws for holding theinserts permits not only rapid and convenient attachment as well asexchange of said inserts, but also, in the case of the use of the holderin conjunction with holding columns, permits the height and/or angularposition of the holder with respect to the holding columns to be set ina fashion adapted to the respective situation.

DESCRIPTION OF THE BEST MODES FOR CARRYING OUT THE INVENTION

In the figures, 1 denotes the basic body of a holder for known (andtherefore not represented) swivel boards which are provided at mutuallyopposite ends of one of their edges with swivel bearings for rows ofpins 2 arranged at the upper and lower edge of the holder. The holdershown has ten pairs of pins, and is therefore suitable for holding tenswivel boards which are constructed, for example, as scale-type boards.In order to permit cost-effective production of the holder, which isconstructed as a plastic injection-moulded part, its rear wall 3 isprovided in the region of the pins 2 with windows 4 which permit theinsertion of injection moulds without splits. In order to lend theholder a satisfactory stability, it is of shell-shaped construction. Ithas end and side walls 5, 6, 7 and 8, constructed from a continuous web,and a central trough 9. In the region of the trough 9, the rear wall ofthe holder comprises two wall sections 10 and 11 which merge into oneanother in the lower third of the holder with the formation of an obtuseangle. Longitudinal struts 12 and transverse struts 13 in the region ofthe trough 9 make a considerable contribution to the stability of theholder. Four transverse struts 13 arranged in the centre of the trough 9and running perpendicular to the longitudinal axis of the holder areprovided with aligned plug-through openings 14 which permit a holdingcolumn to be pushed into the trough 9. Windows 15 are located in thewall section 10, in order also to be able to produce these cutoutscost-effectively. A guide channel 16 for a holding column is let intothe wall section 11. As may be seen from FIGS. 1, 5 and 7, the height Hof the window 4 is greater than the length L, and the width B of thewindow 4 is greater than the diameter d of the pins 2. By contrast, thewidth W of the window 15 is equal to the breadth b of the cutouts 14.

In order to be able to fasten the holder on a wall with the aid ofscrews, the wall section 10 is fitted with cutouts 17 and 18 which areformed by elongated holes and whose longitudinal axes are perpendicularto one another, in order to be able to adjust the position of the holderwithin certain limits.

As already stated, it is desired to be able to fasten the holder notonly on a wall, but also on a holding column. In order to render thelatter possible, in the deepest region of the trough 9 the holder has areceptacle 19, open towards the front side of the holder, forexchangeable inserts 20 and 21, as they are represented in FIGS. 9 and11.

Clamping jaws 22, which are arranged in pairs and between which theroller-shaped inserts 20, 21 can be pressed, serve the purpose offastening the inserts 20, 21 on the holder or in the receptacle 19. Thespacing between the clamping jaws 22 of each pair of clamping jaws istuned in this case to the outside diameter of the respective insert 20or 21 in such a way that the latter can be swivelled into the receptacle19 about its longitudinal axis 23 without being loosened. As may be seenfrom FIGS. 3, 6 and 8, the guide channel 16 let into the wall section 11of the trough 9 opens into the receptacle 19 and is aligned with theplug-through openings 14 in the central transverse struts 13 arrangedperpendicular to the longitudinal axis 24 of the holder. Adjoining theguide channel is a cutout 25 which extends in the base region of thereceptacle 19 and is required in order as indicated in FIG. 10—to beable to swivel the holder about the longitudinal axis 23, and this at anangle α of at most 90°.

The insert 20 represented in FIG. 9 extends over the entire inside widthof the receptacle 19, that is to say its end faces bear in the slidingfit against the inner surfaces, facing them, of the side walls of thereceptacle 19. A holding column 27, which is formed by a tube and isprovided in the region of its ends with transverse bores 28, 29,projects into a transverse bore 26 of the insert 20. The transversebores 28, 29 are aligned with a longitudinal bore 30 of the insert 20. Athreaded screw 33 with a knurled head 34 projects through thelongitudinal bore 30 of the insert 20 and through bores 31, 32 in theside walls of the receptacle 19; a knurled nut 35 is screwed onto theend, averted from the head 34, of the threaded screw 33. It is possibleby tightening the knurled nut 35 to press the side walls of thereceptacle 19 firmly against the end faces of the insert 20 and to lockthe latter in this way in a desired oblique position of the holder withrespect to the holding column 27.

If there is no interest in the possibility of changing the angularposition of the basic body 1 with respect to the longitudinal axis ofthe holding column 27, but is desired merely to render the basic body 1capable of height adjustment by limited amounts in the direction of thelongitudinal axis of the holding column 27, use is made of an insert 21of the type represented in FIG. 11. The insert 21 has a threaded bore 36into which the end of a threaded screw 37 is screwed which, in turn, hasa knurled head 34. By pressing the free end of the threaded screw 37against the circumference of the holding column 27, the position thereofis locked with respect to the insert 21 in a force-closed fashion. FIG.12 shows two positions of the holder offset in height by the amount X onthe holding column 27.
